We are in the process of replacing the requirement of a one semester senior laboratory taken in a narrow area of specialization (ceramics, electronic materials, metals, polymer, or biomaterials) with a Greetings requirement that each student enroll in four ½-semester “lab modules” of their choice. We will be doubling the hours of laboratory instruction from Urbana in the senior year from 3 to 6, essentially replacing one lecture course with three hours of laboratory instruction. The new lab modules are intended to be more dynamic than the relatively static topics that we offered in the past; topics covered in the lab modules will be responsive and reflect changes in the field.

  • Programming Models for Parallel Heterogeneous Computing
    Programming Models for Parallel Heterogeneous Computing Frank Feinbube [email protected] This paper describes my work with the Operating Systems and Middleware group for the HPI Research School on "Service-Oriented Systems Engineering". 1 Motivation Many of the computational problems we are facing today are complex and need huge computational power to be solved. It is well-known that processors will not continue to get faster, but will get more cores instead. More cores are not only harder to utilize by an application programmer, but also challenge hardware designers. Thus various new hardware architectures are designed and evaluated in order to find the ones that will fulfill the needs of future computer systems. Prototypic configuration boards like Intels Single Chip Cloud Computer (SCC) are an attempt to deal with the ever-increasing number of cores by removing essential features of current processors like hardware cache coherency. Another approach is to accompany common general purpose CPUs with sophisticated special purpose processing units. These so called Accelerators are easier to build and very fast for specific application purposes. They are the foundation for the new trend of hybrid computer systems. 2 Domains of Hybrid Systems 2.1 High Performance Computing The High Performance Computing (HPC) community has a steady need for an increase of floating point operations per second (FLOPS) in order to simulate natural processes with a higher accuracy. Therefore enormous computer clusters are used. These su- percomputers are not only very expensive to build, but do also need a huge amount of energy, both for processing and for cooling.
